The CAL Controls 3300 Series temperature controller is a 1/32 DIN autotuning PID controller that comes
standard with two outputs: solid state driver to switch a remote solid state relay (5Vdc +0/-15%, 15mA,
non-isolated) and Relay form A/SPST contacts (2A/250 VAC resistive load). CAL Controls 3300 Series
controllers are powered by a 24V AC/DC or a 100-240VAC power supply.

The CAL Controls 3300 Series temperature controller has the option to add a communications board so that
you can connect your temperature controller to a PC. The best way to use the CAL Controls 3300 Series
temperature controller with a PC is with CAL's data-logging and chart-recorder software CALgrafix.
